I saw Dr. Walker because I’ve been experiencing more severe digestive issues lately. I’ve always had digestive issues so I’ve seen other GI doctors but no one has ever taken the time to really get to the root of my problem. I was so impressed by Dr. Walker and his entire staff when I saw him in the office for the first time. I finally found a doctor that really gets what I’m experiencing. Today I had an endoscopy and colonoscopy. I was so nervous but his team was amazing! The front desk, the prep nurse, anesthesiologists, procedure nurse and my release nurse we’re all so compassionate and professional. I wish I found them sooner. Looking forward to getting my results and feeling better. I highly recommend Dr. Walker and his team!

Dr Walker treated me as a unique individual not just as another case. He recalls what was said in a prior office visit and ask questions to get at the heart of one's condition and concerns. He took the time to return my phone call in person. He diagnosed a condition not related to his specialty that had not been identified by my primary care doctor. He took the time to call my primary care doctor to discuss his observations.
